The House Spider

House spiders are the most common spiders found in peoples living areas. They are usually a yellowish brown with a dirty white abdomen and range from 3.8 to 6 mm long. These pests love hanging around areas that are low in traffic such as high corners, closets, and garages. They usually get in homes from small cracks or holes. House spiders produce a large amount of webs and, if left alone, they can live for over a year.

During a female spiders life, she has the ability to deposit 12 or more egg sacs which each contain 140 to 380 eggs. With the potential of having these many spiders roaming around your home, it’s very important that you take care of an infestation right away. Other details of house spiders is that they have very poor eye sight and like to play dead when they feel they are being threatened.

Signs of an Infestation

A house spider infestation is much more troublesome to have than it is life threatening. The first thing you’ll notice if you have such a problem are an increased amount of webs around your home. If house spiders are outside your home they will most often hang around any kind of shrubs because it’s a great place to hide. When they are indoors, it is most likely because they are trying to cool themselves down from the summer heat. Another area where house spiders will dwell in are cardboard boxes. If you have lots of insects near or around your home, this could also be another call for house spiders, since this is what they feed on.

Understanding the Seasons

Weather has a profound effect on pest life cycle. Most pests, rodents and insects breed aggressively during spring and go through periods of hibernation during autumn and winter.

When the weather slowly begins to heat up, pests start to get more active after having stayed dormant over the colder winter months.

  • Birds often start to find mates and start building their nests.
  • Moths which consumer leaves usually become active again.
  • Flies often emerge from their winter hibernation places and start to breed and spread out.
  • Squirrels also spend the winter in hibernation. When spring approaches these creatures start looking for a new home. This is usually the time when they make their way into lofts and other spaces.

Summer is arguably the best season for pests. It is the time when they are in full swing and breed as rapidly as they can. Wasps are one of the most common summer pests followed by flies and rodents. Many a summer picnics and BBQs have been ruined by the ‘home invasion’ of these pests.

  • Wasps build their nesting grounds and lay their eggs during this time. Although the creatures are not directly harmful, they can be very aggressive and territorial at this time of the year, because they’re at their strongest.
  • The number of fleas also multiplies. Since pets spend more time outdoors during summer, they are more likely to bring the pests back indoors with them.
  • Bees are also more active during summer as they go out to gather nectar. Many times, homeowners find a new beehive in their garden and require pest control to take care of it. Because of their sting, bees are more dangerous than some of the other pests and you should call our professional service to get rid of them.
  • Moths and flies usually start to multiply significantly during summer.
  • Ants begin to swarm to find new mates and start new colonies during summer.
  • Cockroaches become very noticeable in the summer, especially in the kitchen and toilets. This is due to the hotter temperatures and stronger smells.
  • Bedbugs are also very active in the summer.

Autumn is the month when things start to get cooler. The number of pests starts to dwindle as they begin to slow down their breeding activities.

  • Wasps start becoming dozy and docile. You may find them buzzing around occasionally as if they are drunk. This is usually the end-time for their life.
  • Spiders in particular are more active at this time of the year.
  • Squirrels will gather their food and start to look for shelter.
  • The second breeding phase for flies begins. These pests remain active during the season.
  • Rodents also become more active. Due to the approaching cold, rodents usually find shelter inside homes in the loft or inside walls.

The coldest months are when pests seek out warmth and shelter. You will find a number of insects especially rodents and lizards make their way inside your home.

  • Spiders come into our homes to escape the web-destroying frosts.
  • Rodents move indoors to escape the cold, increasing infestations.
  • In many cases, homeowners find squirrels nesting in lofts when they go to get their Christmas decorations.
